Ernest Howard Crosby (1856–1907) was an American reformer, georgist, and author, born in New York City, the son of Presbyterian minister Howard Crosby, and a relative of prolific hymn-writer and rescue mission worker Fanny Crosby.

While a member of the State Assembly (1887–1889), he introduced three high-license bills, all vetoed by the Governor. From 1889 to 1894 he was judge of the Court of the First Instance at Alexandria, Egypt.
